This tutorial will walkyou through the process of importing a WaveFront .obj file that wasexported from DAZ or Poser 6 or version 7. By using the poseriopython programs you can get a really clean import from Poser with outthe need to adjust a lot of materials or uv maps after the import.The script also contains programs that will help you work around the16 material limit in Blender. You can skip step 3 if you are notinterested in how the process works.

Step 1 Setup your environment:

By installing this DAZ Add-On for Poser, users can load Genesis figures directly into Poser. Once the DSON for Poser Importer is installed, Genesis figures that are marked as DSON Importer for Poser compatible can be installed and loaded into Poser just like any other Poser figures.
In this tutorial, you start with a blank Excel workbook. The sections in this tutorial are the following: Import data from a database. Import data from a spreadsheet. Import data using copy and paste. Create a relationship between imported data. Checkpoint and Quiz. At the end of this tutorial is a quiz you can take to test your learning.

Poser 10 is 32 bit only, so you should be installing only the 32 bit version of the importer. DAZの『DSON Importer』の登場により、Poser上で簡単にGenesisフィギュアを読み込めるようになりました。これまでご紹介してきたCR2エクスポーターによる方法とは違い、こちらはDAZ Studio 4.5以降の標準（フォーマット自体は4.0から採用）であり、Genesisフィギュアに使われているDSONフォーマットの.

Updates are for figures with more than 4 vertex per face. A warning is printed in the command window and the face is not created. After import you can add the missing faces.
Unzip to a suitable directory, for example:
Windows: c:blenderstuffposerio
Linux: /home/yourid/blenderstuff/poserio

This package contains the programs to do the imports. It also has an import and export for making Morph Targets in Poser. Those are posermtexport.py and poserimport.py. One note on morph targets, you can only move vertices, do not scale, set smooth, rotate, add or delete anything or poser will fail to apply your morph correctly.

Update your PYTHONPATH to include the new directory created above.
1. If you do not have PYTHONPATH set you can determine what it should include by starting command or shell window (Both linux and Windows) in the directory from step 2.
2. Enter python printpypath.py
3. The output can be used to set your PYTHONPATH environment variable. Make sure you have included the directory that contains poserio programs.
  1. Linux: you can add it to your .profile or .bashrc in your home directory or in the shell before you start blender. The ouput from the command would be cut/pasted into the command: export PYTHONPATH=theoutputhere
  2. Windows: bring up control panel, select system then the advanced tab. At the bottom will be a button for Environment Variables. Select that button and then under User Variables select new. Enter PYTHONPATH for the name and paste the output from the command above.

Step 2 Export from Poser or DAZ:

Blender does have a limit of 16 materials per mesh object. Whenyou complete the import the figure in blender all objects youselected will become one mesh. Later in this tutorial I will havesteps you can follow to collapse materials with the same UV image mapinto one material name. As you select your figures to export plan ahead. You will be better off if you export one figure at a time.

In DAZ or Poser create, pose and apply any textures and expressions you want. Do not use Dynamic Hair, it cannot be imported correctly and will cause parts of your figure to be missing after import.
1. Poser: from the file menu select export, WaveFront OBJ, then single frame. From the Hierarchy Selection panel de-select Universe and select the figure and parts you want to become one object in Blender.
  1. Select a file name the pick the following export options:
  1. Select Ok and the object will be exported.
2. Poser has a python script to copy the scene inventory to a directory, including the materials. From the window menu select Python scripts. From the pop up box select Utility Functions then Collect Scene Inventory. From the Copy all selection item choose the same directory you exported the .OBJ file. When the script is done you can delete the extra items collected if you want. You only need the images, the .obj file you specified and it's associated .mtl file.
3. DAZ: Select File, Export, enter a name for the file. In the export options panel make sure you select the boxes for Write normals and Write UV coordinates.
  1. DAZ will copy the images to a MAP subdirectory in the same location as the .obj file.
Any procedural textures you have used such as 3D clouds, noise etc will not get imported. Those textures will need to be re-applied once in Blender. The import process will turn each Material into a Image Texture so you will be able to easily add back any procedural textures.

Step 3 .obj file and .mtl file background 101:

The import process will make more sense if you have a basicunderstanding of what is in the .obj file and the .mtl file.

OBJ file

The .obj file is a text file thatcan describe 3D objects. Each line of the file is either a comment, aline starting with # or a tag line. The tags we are interested in forthis tutorial are:

mtllib : This tag give the file name of the material lib, .mtl file. The poserio importer expects the file referenced by this line to be in the same path as the .obj file, or be a relative path from the .obj files path.
v : This tag is a vertex coordinate. They will be referenced as a array of tags, starting with the first one found in the file.
vt : A texture vertex coordinate, as with the v tag it will be referenced as an array starting with the first one found in the file.
vn : Vertex normal coordinate, not used by the poserio import process.
f : This is a face tag for creating the faces. The correct format is four pairs of v/vt/vn or v//vn. The number referenced is the index number of the v, vt or vn tags from the start of the file. So 62/1/62 would mean counting from 1 the 62 v tag found, the 1'st vt tag and the 62 vn tag. If there are no UV coordinates then the format is v//vn. DAZ exports incorrectly if you do not select the option for exporting vertex normals. In that case you get v/vt which will crash the poserio import process.
g : This tag is the grouping of all faces. When a g tag is found all the following f tags belong to that group until another g tag is found. The poserio import process does not use the grouping to build separate objects. By making all the objects a single mesh the ugly seams are avoided.
usemtl : The tag that shows which material section out of the .mtl file to use. As with the g tags the same material is used until another usemtl tag is found. This is the key tag to getting around the Blender 16 material limit. Later in the tutorial I have a process that will do a global change of one material to another. If both materials referenced are the same image or exactly the same material they can be collapsed into one. By doing this you do limit your ability to adjust all the material groups, however many of the materials may not need to be worked with individually. For example SkinHead and SkinScalp could be combined with no loss in most cases.

MTL file

The .mtl file is a textrepresentation of all the materials used in the figure. Even if youexport only one part of the figure the .mtl file will have a fulllist of all the materials used in the figure. The tags of interest inthis tutorial are:

newmtl : This tag starts a section, the name following the tag is the material name, same one referenced in the usemtl found in the .obj file. All tags following this one belong to that material until another newmtl tag is found.
map_Kd, map_d, map_Bump : These tags point to the image file
